Mercedes crew principal Toto Wolff says the Brackley squad remains to be unsure whether or not it has absolutely addressed its automobile’s longstanding sensitivity to trace situations.
Talking in the course of the FIA crew principal press convention on the second day of pre-season testing in Bahrain, Wolff mirrored on an unusually chilly surroundings that has thrown a curveball into their evaluations.
With Bahrain not internet hosting the season opener – Australia takes that honor on March 16 – the unrepresentative climate has left Wolff questioning whether or not Mercedes’ previous benefit in cooler situations stays intact or if their automobile is lastly discovering stability throughout a wider vary of temperatures.
Traditionally, Mercedes has struggled with inconsistency underneath the bottom impact laws launched in 2022, usually flashing race-winning tempo in follow solely to fade over race weekends.
Final yr, a transparent sample emerged: the crew thrived in cooler situations, reminiscent of Las Vegas, however faltered when the mercury rose.
Bahrain’s surprising chilly snap provided a theoretical edge, but Wolff stays cautiously skeptical about their progress.
A Cool Take a look at, However No Clear Solutions
Addressing the untypically chilly temperatures which have prevailed this week in Bahrain, Wolff jokingly prompt that Mercedes’ W16 ought to be dominating the timesheets.
“Properly, I’m a bit anxious in the mean time as a result of that ought to be situations the place we’re two seconds faster than everybody else which was the one spotlight final yr by way of efficiency in Las Vegas and we’re not,” he mentioned.
The shortage of a standout benefit has left him pondering two potentialities.
“Both manner we’ve remedied the issue and we’re extra balanced by all of the weather conditions, or not. We had amusing about whether or not we’ve misplaced a few of that USP (distinctive promoting level).”
The Brackley squad’s kind in Bahrain hasn’t supplied a definitive reply, with Wolff admitting the jury remains to be out.
The cooler-than-usual take a look at has muddied the waters, making it troublesome to gauge whether or not their improvement path has actually neutralized the automobile’s temperature sensitivity.
Chasing Predictability Amid Unrepresentative Situations
Regardless of the paradox, Wolff sees glimmers of progress in tackling one other persistent concern: the automobile’s unpredictability.
Mercedes’ 2024 marketing campaign was stricken by a machine that might dazzle in a single session and disappoint within the subsequent, no matter monitor situations, usually leaving drivers and engineers scrambling.
Wolff believes they’ve taken strides – nevertheless small – towards a extra constant platform.

“I believe generally you are taking junctions which go within the incorrect course,” he famous. “Possibly yesterday we tried one thing within the afternoon which didn’t perform.
“It’s about having a automobile that provides extra confidence and that was the factor we have been lacking final yr. It was unpredictable and that appears a tiny step forward.”
But, he tempered this optimism with a nod to the testing surroundings’s limitations.
“Like all of you mentioned, we don’t know about gasoline masses. Yesterday [on day one], Norris was on a unique planet. Very, superb. Lewis, this morning [on day two]. Sainz on the C2 tyre was very spectacular so you actually don’t know.
“The situations are completely not consultant.”
These variables—rival efficiency, gasoline unknowns, and atypical climate—complicate any agency conclusions about Mercedes’ standing.
With Australia’s hotter local weather looming, the opening race will function a essential litmus take a look at. For now, Wolff and his squad can solely hypothesize—have they misplaced their edge within the chilly, or gained a broader stability? Solely time, and some extra laps, will inform.
